Operation

CAUTION
The flux chipper must be properly lubricated before operation. See “Lubrication” section.

1. Push retainer lever (Figure 1) and insert chisel. Release retainer lever to secure chisel. Grasp chisel and attempt to pull it out to ensure that it is secure.
   Note: The chipper body may be oriented for best comfort of the user’s hand on the throttle lever; orient the chisel accordingly.

2. Remove protective cap from air inlet (Figure

3. If an in-line oiler is not being used, add 4 or 5 drops of air tool oil (not included) into the air inlet.

4. Blow out air line to remove any dirt or moisture, then connect air supply hose to tool. Set air pressure to 90 psi.
   IMPORTANT: Connecting a quick-change coupling directly to the tool is not recommended, as vibration may cause the connection to fail. Instead, add a leader hose and install any quick-change couplings farther down the line.

5. Hold flux chipper firmly with both hands and rest chisel tip against work surface.

6. Press throttle lever. Pressure against throttle lever determines speed of tool. Do not exert excessive pressure against work surface – let the tool do the work.

7. Release throttle lever to stop flux chipper.

8. To remove chisel, push retainer lever.

Maintenance

Lubrication
The flux chipper should be lubricated daily (or before each use) with air tool oil through the air inlet. During continual operation, it should be reoiled every 1 to 2 hours. This can be done with an in-line oiler, or manually. If done manually, proceed as follows:

1. Disconnect air hose from tool.

2. Place 4 or 5 drops of air tool oil into air inlet.
   NOTE: Air tool oil not provided; it is available at most major hardware and tool stores. SAE #10 oil or sewing machine oil may be used as a substitute. Do not use detergent oil.

3. Re-connect air. Run flux chipper at low throttle without load for a few seconds to distribute the oil throughout tool.

4. When finished operating flux chipper,disconnect air hose. Wipe off housing with a dry cloth. Place 4 or 5 drops of air tool oil into air inlet; re-connect air and run tool for a few seconds to distribute the oil. Disconnect air.

Storage
Avoid storing the flux chipper in very humid locations which promotes rusting of internal mechanisms. Always oil the tool and disconnect air hose before storage.

Air system requirements

1. Use proper air hose size (refer to tool specifications). The hose should be just long enough to serve the working area. Excessive hose length will cause pressure drop.

2. Make sure air compressor supplies clean, dry air at correct CFM for the tool.

3. Set air pressure to 90 psi.
   CAUTION
   Excess air pressure and/or unclean air will shorten the tool’s life and may create a hazardous situation.

4. Drain water from air compressor tank daily, as well as any condensation from air lines.
   Water in the air line may enter the tool and cause damage.

5. Change filters on the air system on a regular basis.

6. Air-line pressure may be increased accordingly to compensate for extra-long air hoses (usually over 25 feet). Inside diameter of hose should be minimum 3/8-inch.

General Air Tool Information

If the air tool is not performing according to specifications, the following are among the most common causes. (See also “Troubleshooting” section.)

• Contaminated air such as a dirty air system or water in the system.
• Using wrong size tool for the job.
• Poor maintenance practices, such as using excessive air pressure or air volume.
• Improper or no lubrication.

Rule of Thumb
If it takes more than 8 seconds to tighten or loosen a bolt or nut with an air impact wrench at maximum setting, the air wrench is too small or the air compressor CFM is not powerful enough for the job. Continued use in either capacity will
cause damage to the tool.

Tool Pressure
JET Air Tools operate on 70-to-100 psi (pounds per square inch) air pressure measured at the tool when the tool is operating. Set tool to 90 psi unless indicated otherwise. Pressure in excess of 100 psi will shorten the life of the tool.

Air System Recommendations
Equip the air compressor intake with a replaceable air filter that can be easily cleaned.
Use safety shut-off valves so air flow can be stopped quickly in case of a line break.
When using multiple hoses, air hoses should be larger than leader hose. Join multiple hoses directly, rather than with quick connect fittings which may cause pressure drops and tool power reduction.
Use anti-whip devices across hose couplings to prevent hose from whipping in the event of a hose failure or coupling disconnect.
Always use moisture traps at the compressor for the main distribution line. Use moisture traps and in-line oilers on each downline that is to be used for air tools. (See Figure 2). Place oiler as close to air tool as possible for best lubrication.

Lubrication
Use a light oil containing rust inhibitors, such as SAE #10. Many JET air tools have integral oil reservoirs, which should be kept filled when in-line oilers are not used.
If greasing is required, use a grease that is highly water resistant for front case components on air impact wrenches, grinders and sanders.

Recycling
Protect the environment. Your tool contains materials which can be recovered or recycled.
When its useful life has expired, please leave tool at a specialized facility.
